Project description:Introduction and aimsNeedle-syringe programs (NSP) are an underutilized source of data on drug injection trends; these data are essential for informing public health interventions. We examine trends in NSP service occasions from 2007-2015.Design and methodsUsing standardised data from 26 NSP outlets through the Queensland NSP Minimum Data Set (QNSPMDS), trends in service occasions among clients intending to inject methamphetamine, heroin, opioid substitution therapy (OST) medications and other pharmaceutical opioids were assessed using multilevel mixed-effects negative binomial regression, adjusting for month, year, age and clustering by site.ResultsOver 1.5 million service occasions were recorded in 2007-2015. Methamphetamine was the main 'drug intended to inject' (33.7%), however cf. 2007, the incidence rate ratio decreased to 0.64 (95% CI: 0.62, 0.66) in 2009, remaining low until 2015. Among clients reporting methamphetamine injection, there was a shift in the form from base to the higher-potency crystal methamphetamine since 2012. Heroin injection (22.5% service occasions) initially increased (cf. 2007), followed by a decline to 0.77 (95% CI: 0.75, 0.79) in 2015. Significant and sustained increases in OST and other pharmaceutical opioids injection were observed throughout the study period, accounting for 7.2% and 19.8% of total visits, respectively.Discussion and conclusionsThe QNSPMDS provides unique, routinely collected, jurisdiction-wide and standardised data on the demographics of people who inject drugs, types of drugs injected and regional variations; these data are essential in informing policy, planning and program implementation. There remains significant opportunity to enhance engagement and linkage to care alongside needle-syringe provision.

Project description:BackgroundIn the context of increasing syphilis rates, particularly among Black men who have sex men (MSM), the objectives were to determine the associations between methamphetamine (meth) use and syphilis and HIV positivity, and to identify sex partner meeting venues as potential intervention access points among Black MSM in a mid-Atlantic US city.MethodsThis study is an ongoing longitudinal cohort study. Participants were recruited from clinical and nonclinical settings and included sexually active MSM aged 18 to 45 years. The baseline visit included a behavioral survey and testing for syphilis, HIV, gonorrhea, and chlamydia. Logistic regression analyses were used for hypothesis testing.ResultsAmong 359 MSM completing baseline, 74.4% (268) Black MSM were included; 31% (84) were aged 24 to 29 years, 43.7% (117) reported unprotected anal intercourse at last sex, and 15.3% (41) reported meth use in the past 3 months. Sixteen percent (43) had syphilis, 46.6% (125) were living with HIV, and 19.0% (51) had gonorrhea and/or chlamydia. Meth use was associated with sexual and drug risk behaviors and HIV, but not syphilis. In adjusted analyses, meth use increased the odds of HIV positivity by 6.43 (95% confidence interval, 2.30-17.98) and syphilis positivity by 2.57 (95% confidence interval, 1.23-5.37). Four online sex partner meeting venues were associated with meth use and HIV, whereas syphilis was associated with one.ConclusionsAmong Black MSM, meth use and syphilis positivity were associated with more than 6-fold and almost 3-fold increased adjusted odds of HIV positivity, respectively. Four specific sex partner meeting venues may be important access points for HIV/sexually transmitted infection and substance use prevention.

Project description:We investigated gay and bisexual men's willingness to self-administer an anal cancer screening test at home.We conducted 2 national, online cross-sectional surveys of self-identified gay and bisexual men: Study I in 2009 with men ages 20 to 59 (n = 306) and Study II in 2013 with men ages 18 to 26 (n = 428). We used multivariate logistic regression analyses to determine variables associated with willingness to self-administer the screening test.Most men were willing to self-administer an anal cancer screening test (78% Study I; 67% Study II). In Study I, willingness was higher among men who trusted anal Paps to find treatable cancer (adjusted odds ratio [aOR] = 1.47; 95% CI, 1.04-2.09) and who believed that men who have sex with men should be screened for anal cancer between 1 and 3 years vs. other intervals (aOR = 2.19; 95% CI, 1.17-4.10). In Study II, willingness was higher among men who perceived greater likelihood of anal cancer (aOR = 1.57; 95% CI, 1.12-2.20). Their most common concerns were not performing the test correctly and inaccuracy of results.Many gay and bisexual men were willing to self-administer anal cancer screening tests at home. If routine screening is warranted, self-collected home testing could improve participation.

Project description:Previous studies suggest that male testosterone concentrations have declined over time. To explore this in a large US population, we examined testosterone and free testosterone concentrations in National Health and Nutrition Examination Surveys (NHANES) from 1988-1991 and 1999-2004. We also examined sex hormone-binding globulin (SHBG), estradiol, and androstanediol glucuronide (3?-diol-G) over the same period. Non-Hispanic white, non-Hispanic black, and Mexican-American men from 1988-1991 and 1999-2004 NHANES surveys who were ?20 years old and had serum from morning blood draws were included in this analysis (1988-1991: N = 1,413; 1999-2004: N = 902). Testosterone, estradiol and SHBG were measured by competitive electrochemiluminescence immunoassays and 3?-diol-G was measured by enzyme immunoassay. Free testosterone was calculated using testosterone and SHBG values. Adjusted mean hormone concentrations were estimated using linear regression, accounting for NHANES sampling weights and design, age, race/ethnicity, body mass index, waist circumference, alcohol use and smoking. Differences in adjusted mean concentrations (?) and two-sided p-values were calculated; p < 0.05 was statistically significant. Overall, 3?-diol-G and estradiol declined between 1988-1991 and 1999-2004, but there was little change in testosterone, free testosterone, or SHBG (?: 3?-diol-G = -1.83 ng/mL, p < 0.01; estradiol = -6.07 pg/mL, p < 0.01; testosterone = -0.03 ng/mL, p = 0.75; free testosterone = -0.001 ng/mL, p = 0.67; SHBG = -1.17 nmol/L, p = 0.19). Stratification by age and race revealed that SHBG and 3?-diol-G declined among whites 20-44 years old (?: SHBG = -5.14 nmol/L, p < 0.01; 3?-diol-G = -2.89 ng/mL, p < 0.01) and free testosterone increased among blacks 20-44 years old (?: 0.014 ng/mL, p = 0.03). Estradiol declined among all ages of whites and Mexican-Americans. In conclusion, there was no evidence for testosterone decline between 1988-1991 and 1999-2004 in the US general population. Subgroup analyses suggest that SHBG and 3?-diol-G declined in young white men, estradiol declined in white and Mexican-American men, and free testosterone increased in young black men. These changes may be related to the increasing prevalence of reproductive disorders in young men.

Project description:PurposeTo evaluate the association between mental health services (MHS) use and depressive symptom scores among gay and bisexual men (GBM) and compare with heterosexual men in Canada.MethodsWe used data from the 2015-2016 cycles of the Canadian Community Health Survey. Depressive symptoms were assessed using the PHQ-9 questionnaire (prior two weeks). MHS consultations with any licensed mental health professional (prior year) were categorized as 0, 1, 2-11, ≥ 12. We fit linear regression models to quantify the associations between MHS use and PHQ-9 scores, with an interaction term for sexual identity (GBM and heterosexual men). Models were adjusted for socioeconomic and health-related indicators.ResultsAmong 21,383 men, 97.3% self-identified as heterosexual and 2.7% as GBM. Compared to heterosexual men, GBM used any MHS (21% vs. 10%, p < 0.05) and consulted ≥ 2 health professionals for their mental health (6% vs. 2%, p < 0.05) in the preceding year more frequently. Overall, mean PHQ-9 scores were higher among GBM compared to heterosexual men (3.9 vs. 2.3, p < 0.05). Relative to no consultations, higher MHS use (2-11, ≥ 12 consultations) was associated with higher PHQ-9 scores (1.4-4.9 points higher). Associations between MHS use and PHQ-9 scores did not differ statistically between GBM and heterosexual men.ConclusionOur findings were inconclusive in demonstrating a difference between heterosexual men and GBM for the association between MHS use and PHQ-9 scores. However, GBM consistently had higher average PHQ-9 scores for every category of consultations. Considering the higher use of MHS and higher burden of depressive symptoms among GBM, more research is needed.

Project description:ContextLesbian, gay, bisexual, and transgender (LGBT) people are at increased risk for the adverse effects of tobacco use, given their high prevalence of use, especially smoking. Evidence regarding cessation is limited. To determine if efficacious interventions are available and to aid the development of interventions, a systematic review was conducted of grey and peer-reviewed literature describing clinical, community, and policy interventions, as well as knowledge, attitudes, and behaviors regarding tobacco use cessation among LGBT people.Evidence acquisitionEight databases for articles from 1987 to April 23, 2014, were searched. In February-November 2013, authors and researchers were contacted to identify grey literature.Evidence synthesisThe search identified 57 records, of which 51 were included and 22 were from the grey literature; these were abstracted into evidence tables, and a narrative synthesis was conducted in October 2013-May 2014. Group cessation curricula tailored for LGBT populations were found feasible to implement and show evidence of effectiveness. Community interventions have been implemented by and for LGBT communities, although these interventions showed feasibility, no rigorous outcome evaluations exist. Clinical interventions show little difference between LGBT and heterosexual people. Focus groups suggest that care is needed in selecting the messaging used in media campaigns.ConclusionsLGBT-serving organizations should implement existing evidence-based tobacco-dependence treatment and clinical systems to support treatment of tobacco use. A clear commitment from government and funders is needed to investigate whether sexual orientation and gender identity moderate the impacts of policy interventions, media campaigns, and clinical interventions.

Project description:Purpose: This study aimed to characterize the patterns of smoking, e-cigarette use, other substance use (alcohol and marijuana), and depression by sexual orientation in a sample of Mexican adult smokers. Methods: Data came from a 2018-2020 (six waves) online survey of adult smokers, recruited from a commercial research panel (92.5% heterosexual, n = 4786; 3.1% lesbian/gay, n = 160; and 4.4% bisexual, n = 229). After stratifying the data by sex, logistic, multinomial, and linear logistic regression models were estimated (depending on the outcome), including as independent variables sexual orientation (i.e., gay/lesbian, bisexual, heterosexual = Reference), age, education, household income, and wave. Results: Being a gay male was independently associated with greater smoking dependence (β = 0.20; 95% confidence interval [CI]: 0.02 to 0.39), greater likelihood of preference for flavored capsule cigarettes (adjusted odds ratio [AOR] = 2.10, 95% CI: 1.33 to 3.28), and depression diagnosis (AOR = 2.85, 95% CI: 1.64 to 4.95). Bisexual males had higher e-cigarette dependence (β = 0.37; 95% CI: 0.05 to 0.68, among dual users only) and were more likely to have been diagnosed with depression (AOR = 2.34, 95% CI: 1.30 to 4.18). Lesbian females were more likely to prefer menthol cigarettes (AOR = 3.32, 95% CI: 1.60 to 6.86), to have used marijuana more than once (AOR = 3.23, 95% CI: 1.83 to 5.72), and to have depressive symptoms (AOR = 1.85, 95% CI: 1.04 to 3.29). Bisexual females had a greater likelihood of depressive symptoms (AOR = 1.71, 95% CI: 1.14 to 2.56) and depression diagnosis (AOR = 2.22, 95% CI: 1.43 to 3.42). Conclusion: Lesbian, gay, and bisexual adult smokers in Mexico appear more likely than heterosexual adult smokers to report having depression. Substance use and depression among sexual minority populations need to be addressed further.

Project description:Substance use has become a major health problem globally for sexual minorities. However, few studies have explored multi-dimensional factors associated with smoking, drinking, and prescription drug use. We aimed to investigate the factors affecting painkiller, sedative/hypnotic, nicotine and unhealthy alcohol use among gay and bisexual men in Taiwan. We recruited 500 gay or bisexual men and assessed their experiences of using painkillers, sedatives/hypnotics, nicotine, alcohol and multi-dimensional factors with self-reported questionnaires. Multivariate logistic regression with a forward stepwise model was used to verify the factors associated with substance use. Overall, 9.4%, 5.4%, and 13.8% of the participants reported using painkillers, sedatives/hypnotics, and nicotine, respectively, and 5.6% reported unhealthy alcohol use. Victims of traditional homophobic bullying in childhood and adolescence were more likely to report nicotine use, sedative/hypnotic use, and unhealthy alcohol use in early adulthood than non-victims. Missing classes or truancy at senior high school was associated with painkiller and sedative/hypnotic use in early adulthood. Traditional homophobic bullying and missing classes or truancy in childhood and adolescence predicted substance use in early adulthood among the gay and bisexual men in this study. Timely preventions and interventions for substance use are crucial for gay and bisexual men, especially for those who experience homophobic bullying and missing classes or truancy.

Project description:McKirnan's Cognitive Escape Theory (1996) is often characterized by the hypothesis that drugs are used during sex by gay, bisexual, and other men who have sex with men (gbMSM) to relieve internal cognitive conflict over safe-sex norms and sexual desire. We examined how McKirnan's Cognitive Escape Scale (CES) is related to other widely used constructs relevant to sexualized substance use with hopes of better situating the theory within the evolving landscape of HIV-prevention. Associations between CES and trait anxiety, depression, treatment optimism, sexual altruism, sexual sensation seeking, and self-perceived risk for HIV transmission/acquisition were tested. Mediation analyses tested whether associated psychological measures mediated the effect of CES on the proportion of events in which participants reported co-occurrent substance use and condomless anal sex. Results indicated that CES is associated with higher sexual sensation seeking, treatment optimism, trait anxiety, and perceived likelihood of HIV transmission/acquisition. Mediation analyses suggest that CES is related to but operates independently of treatment optimism, sensation seeking, and trait anxiety. Nevertheless, the intersection of HIV-related worries and substance use expectancies are clearly more nuanced than is widely reported is discussions on cognitive escape.

Project description:ImportanceWith increasing e-cigarette use among US adolescents and decreasing use of other tobacco products, it is unclear how total use of nicotine products, and its long-term health risks, have changed. The Centers for Disease Control and Prevention's standard measure-any tobacco product use in the past 30 days-considers neither frequency of use nor product risk implications.ObjectiveTo investigate how nicotine product use, including frequency of use, and its associated risks have changed among middle school and high school students since 1999.Design, setting, and participantsThis cross-sectional study used data from the 1999-2020 National Youth Tobacco Survey, an in-school survey of a nationally representative sample of students in grades 6 through 12; each survey recruited between 15 000 and 36 000 participants.ExposuresNicotine product use in the past 30 days.Main outcomes and measuresUse of nicotine products assessed by nicotine product days (NPDs), the number of days that the average student consumed these products in the past 30 days. Risk-adjusted NPDs account for differential long-term health risks of various products.ResultsThis study included 16 years of cross-sectional survey data. Each survey recruited between 15 000 and 36 000 participants in grades 6 through 12 (male students: mean, 50.4% [minimum, 48.5%; maximum, 58.4%]; mean age, 14.5 years [minimum, 14.0 years; maximum, 14.7 years]). Nationally representative cross-sectional data for high school students showed that NPDs decreased steadily from 5.6 days per month in 1999 (95% CI, 5.0-6.2 days per month) to 2.2 days per month in 2017 (95% CI, 1.9-2.6 days per month), increased to 4.6 days per month in 2019 (95% CI, 4.1-5.1 days per month), and then decreased to 3.6 days per month in 2020 (95% CI, 3.0-4.1 days per month). For a risk weight of 0.1 for e-cigarettes, compared with combustible products, risk-adjusted NPDs decreased from 2.5 days per month in 2013 (95% CI, 2.2-2.9 days per month) (prior to the popularity of e-cigarettes) to 2.0 days per month in 2019 (95% CI, 1.6-2.5 days per month) and 1.4 days per month in 2020 (95% CI, 1.0-1.8 days per month). However, with a risk weight of 1.0 for e-cigarettes (identical to that of combustible products), risk-adjusted NPDs increased to 5.3 days per month in 2019 (95% CI, 4.4-6.2 days per month) and 3.9 days per month in 2020 (95% CI, 3.1-4.7 days per month). Similar trends were found for middle school students.Conclusions and relevanceThis study suggests that NPDs represent an improvement, albeit an imperfect one, compared with any 30-day tobacco product use by incorporating the frequency of use of various products. By distinguishing products, NPDs permit consideration of the health consequences associated with different mixes of products over time. Health risks of adolescent nicotine product use could have decreased during vaping's popularity if assessment of the long-term risks associated with vaping compared with those of smoking is low. There is a need to closely monitor youth nicotine and tobacco product use patterns.
